Yes, I did and it has been working!!!But I didn't figure out where to place the behavoir file (.htc) and the "blank" image. I just copied both files into all folders so I didn't need to care about file structure. That DHTML 4 Menu has a folder skin, where the relevant stylesheets for the menu are in (winclassic.css). You have to add the png behavior in that file too. Otherwise it does not work. Hope that's the problem.......

Hi!Simply use the PNG Behavior published on this site (webFX). You don't need to understand how it work, just link it to your images by adding a stylesheet like: img { behavior:url(pngbehavior.htc) }.....

BUT:If you load the images before you put them in the menu, the effect won't work. Example: You load the content of the menu folders in your document and copy the content by something like innerHTML into the menu folder. The point is: The Behavior triggers on propertyChange, which works when the image is loaded first. If you copy the source you don't copy the right image (hard to explain)..... ;-)Maybe you don't need to know..... if so, ask for that again - there's a simple workaround!
